Dermatitis (Skin Inflammation)

Dermatitis is a group of inflammatory disorders that affect the skin. It can result from allergy, infection, autoimmune disorders or other causes that lead to skin redness and itching. Atopic dermatitis is an example of allergic dermatitis, while seborrheic dermatitis can be caused by fungal infection.

An overview of the most common types of dermatitis and their clinical presentation is provided in this course. Join now!

Content

Allergic contact dermatitis is a delayed cell-medicated immune reaction from exposure to contact allergens. The substances that trigger ACD can be nickel, poison ivy and fragrances. ACD of acute onset usually represent erythema, pruritic vesicles and bulla whereas lichen with cracks and fissures are seen in chronic cases. Symptoms usually disappear with avoidance of known causative substance. Localized application of mid or high potency topical steroids like triamcinolone and clobetasol relives the acute ACD. Systemic steroid therapy is required in long standing and relapsing ACD. Patch testing is recommended if treatment fails.

Atopic dermatitis is a common, chronic dermatological disorder of unknown origin characterized by intense itching and eczematous lesions. In this chapter, after an introduction to general terminology for skin lesions, epidemiology, clinical features, diagnosis and management of atopic dermatitis are briefly discussed. As the diagnosis is purely clinical, differentiation from alternative diagnoses is also important. Emollients, topical corticosteroids and trigger avoidance constitute the mainstay of management.

Seborrhoeic dermatitis is a common chronic papulosquamous dermatosis with distinct infantile and adult forms, easily recognised clinically. Owing to its frequent recurrence in patients with HIV and AIDS, a careful evaluation of this pathology is warranted. The disease varies from mild to severe exhibiting a variety of forms including psoriasiform, pityriasiform and erythroderma.

There are many disorders of the sebaceous glands. Acne is the most relevant condition in the field of dermatology that is tested in medical examinations. Acne vulgaris is also considered one of the most common skin diseases. The clinical picture of these conditions as well their treatment is covered in this article.

Psoriasis in children is a chronic inflammatory condition of the skin that is characterized by silvery skin lesions over the extensor surfaces of the elbows and knees in children. On the other hand, seborrheic dermatitis is a chronic skin condition that is characterized by acute exacerbations and is believed to be related to an abnormal immune response to the fungus Malassezia. It is marked by patchy scales formed in sebum rich areas of the scalp, face and trunk in a pattern. Patients with seborrheic dermatitis usually present with dandruff or facial greasy skin lesions. Both conditions are diagnosed based on clinical features in children without any sophisticated laboratory evaluation. Both conditions respond to topical corticosteroids. Topical antifungal therapy has been found to be successful in the management of seborrheic dermatitis in children.

Unique

By Rahmah B. on 24. September 2018 for Atopic Dermatitis

I think he is one of the top lectures that have a particularly unique way in gaining attention. Kudos

Seborrheic dermatitis

By Lyndon O. on 29. August 2018 for Seborrheic Dermatitis

Belabors the points quite succinctly! The approach is just the best for clinical dermatology!

Needs discussion about investigations

By Vish V. on 19. August 2018 for Allergic Contact Dermatitis

Would like to see some discussion about investigations eg patch testing

informative lecture

very good and informative lecture. thank you for good explanation associated with the differential diagnosis

very good and informative lecture. thank you for good explanation associated with the differential diagnosis

Nice overview.

By Vidar d. on 01. April 2018 for Seborrheic Dermatitis, Psoriasis and Impetigo in Children

Nice summary of most common rashes in children. Nice recap questions.

Articulate and engaging style of speaking

By Hala A. on 20. November 2017 for Atopic Dermatitis

I don't think he's robotic at all. The way he talks keeps me engaged, better than most monotone professors I have in med school Excellent explanations. He is very articulate and knows how to tie facts together and emphasises on the key facts so you at least leave the video knowing what Atopic Dermatitis is about

excellent presentation

By Courtney W. on 17. September 2017 for Seborrheic Dermatitis

I love how he directly emphasizes main points with repetition and gives details of differentials. He is very direct and to the point, no wasted time.

Smoothly presented lecture, good content, could use some additions

By George L. on 14. May 2017 for Atopic Dermatitis

Good lecture. The talking is very smooth and continuous not robotic like it sometimes tends to be the case with Dr.Raj. Excellent! Good explanation of the terms and the difference between atopic and contact dermatitis!
Some more elaboration on treatment options, including non-pharmacologic and the role of allergen testing (should you do it or not?) would be a good addition.

Good, need more information

By Febelia Devina S. on 19. April 2017 for Atopic Dermatitis

Easy to understand. I recommend adding more information regarding medication such as what kind of systemic seroid we are using.

Non-pharmacological options

By Hamed S. on 07. April 2017 for Atopic Dermatitis

Fantastic talk but would have liked further information on non-pharmacological treatment and also the role of allergen testing

Like the use of DDX

By Hamed S. on 07. April 2017 for Seborrheic Dermatitis

I find one of the challenging aspects of dermatology is to keep in the various ddx for "similar" looking presentation. The way these lectures are set out has been very useful to have a few ddx to think about when facing a pt with a rash!
